Specification of Application filed August'8,

To all whom it may concern:

Be it known that I, GUSTAV Paco-Hesse, a subject of the Emperor of AustriaHungory, and a resident of the city of New York, borough of Brooklyn, in'the county of Kings and State'of New York, have invented a new and Improved Engine, of which the following is a full, clear, and exact description.

This invention relates to rotary engines and hasreference more particularly to a rotary en 'ne of the internal combustion type in whic the power developed'by the motive fluid-is rendered effective through aturbine element.

The invention also relates to arotary en-' gins in which is combined a turbine'element with a motive iiuid chamber of variable; capacity for compressing the motive fluid prior to its, expansion when exploded and utilized in the turbine element. 1

The invention further relates tof th com-{ bination in'a rotary engine, of a telescopic member, means for guiding the member-in a rotary path, and a turbine for utilizing an explosive mixture compressed by said telescopic member.

More specifically the invention relates to a rotary engine having a main rotor provided with a motive fluid chamber, a secondary rotor movable with themain rotor and eccentric with respect thereto, so as tovary the capacity of the motive fluid chamber and adapt the same for use as a compression chamber, and a turbine element adapted to receive motive fluid under compression from the motive fluid chamber. 7

An object of the invention is to provide a simple and efficient rotary engine which is in effect a turbine, which is compact in form and light in Weight, bv means of which the energy of the motive fluid is utilized as completely as possible, in which the expansive force of the motive fluid is rendered fully effective, which may comprise oneor more units operating simultaneously, and it so desired, constituting successive stages. for multiple expansion, and in which each unit; can be provided with a number of workin chambers in which the cycles of operation; are successively carried out. c

A further object of the invention is to? combine in an engine a turbine of any, (1e

a secondary rotary member forming together a variable motive fluid chamber adapted to deliver to the turbine fluid under compression, and ready to be exploded so that the expansive force of the motive fluid can then'be utilized in the turbine element.

The invention consists in the construction and combination of parts to be more fully deseribedbereinatter and particularly set forth and claimed.

Reference isto be had to the accompanying drawings forming apart of this specification, in which similar characters of referenc'eindiczite corresponding parts in all the -vieWs, and in which Figur v l is a vertical longitudinal section "of an engine constituting an embodiment of 'my invention;- and Fig. 2 is a transverse 'vrtical section of the engine.

. Before proceeding to a more detailed ex- ;plana'tionot my invention, it should be Qle'aniy understood-that the present form of the-device constitutes a modification of or an improvement upon the types of engines disclosed in *my co-Qpending applications for Letters Patent of the United States, filed October 10, 1912, Serial No. 724:,955. As in the constructions'there disclosed, the present embodiment of my invention includes two relatively movable rotary. elements which constitute a variable motive fluid chamber into'avhic'h the hydrocarbon gas and air mixture'is drawn and then compressed to be delivered when ready for ignition, to a-turbine element in which the force developed element of course being likewise a rotary member and adapted for transmitting its power directly or indirectly to asuitable point of utilization. I

\Vhile the engine is preferably designed for use as an internal combustion motor, gas steam, air or other fluid under pressure can be utilized therein as will be readily understood. i

In the present application, Ihave illustrated but one construction embodying the relatively movable members which form the variable motive fluid chamber, but in their place may be employed for example any one of the others illustrated in my co-pending application referred to, or any one adapted for the purpose not shown therein. Simisired'or preferred type with a primary and larly, while I have illustrated-aspiral turby the motive fluid is utili'zed, the turbine bine, any other form of this prime mover may be utilized. Y

The present form of the engine may be termed a single-stage .engine', although it combines two separate units each ofwhich is" :practically independent of the other. Should it be desired, however, two or more units may be'coupled in such a manner that the motor is a multiple expansion engine, and the unit or units after the first one utilize exhaust motive fluid.

Referring more particularly to the drawings, I have shown a form of my invention comprising a suitable base'lO having separated upwardly extending abutments 11 between which is received and mounted a substantially circular engine casing. Resting 'upon the, abutments are respectively two substantially circular casing heads 12 and 13. Disposed between the casing heads and movably associated therewith are two substantiallysemi-circular elements 14 and 15 having the edges movably and guidingly received in peripheral inner grooves or recesses 16 and 17 of the casing heads 12 and 13. The casing head 12 has a central, inwardly disposed annular. extension 18 receiving a bearing collar 19 and constituting a bearing for the spindle end 20 of an exhaust cylinder 21 concentric with the axis of the engine. The opposite end of the exhaust cylinder has mounted thereon a hearing collar 22 received in a central bearing 23 of the casing head 13, the bearing 23 being formed within a circular outward extension of the head. The latter has an out- .letopening 24 which communicates with ing laterally dispos d flanges 27 and 28. the

latter considerably less in transverse dimension than the former. The flanges 27 have the outer faces rounded and are inclose sliding contact with the inner surface of the cylindrical casing. The flanges 28 on the other i and are in similar engagement with the outersin'face ot a turbine cylinder 2.)

arranged concentrically within the engine casing about the exhaust cylinder 21. The turbine cylinder is. like the casing heads 1:. and 17%. fixed, and does not turn as will be pointed out hereinafter. The secondary rotor consists of a number of members 30 of arcuate cross section arranged substantially axially Within the casing between adjacent partitions 26. The said members are interrounded bearing strips 82, each engaging one of the partitions 26. The circular portions 30 of the members 30 are received in eccentrically disposed guide grooves 33 ofthe casing head 13, and an annular wall 35 arranged within thecasing 1415 and spaced inwardly from the casing head 12. As the rotors revolve the members 30 move inwardly and outwardly in substantially radial directions owing to the fact that the guide grooves are eccentric with respect to the axis of the casing. The partitions move toward or away from each other as the members 30 alter their positions, so that in this way the efi'ective capacities of the working chambers formed between the adjacent partitions, the members 30 and the turbine cylinder; are varied. These changes in the effective capacities are utilized for drawing in the motive fluid charges and compressing the same as will be pointed out hereinafter.-

lVhile I have described themain and secondary rotary elements respectively in the singular, it 'will be noted that the present formof engine provides two sets of the same spaced by a central radially extended partition34 of the turbine cylinder 29, this partition extending to and engaging the inner wall of the casing 14-15.

The cylinder spindle 20 between the wall and the bearing 18 has a pinion 36'integral therewith or rigidly secured thereto. This pinion is in mesh with a pair of gears 37 each mounted upon a stub shaft 38. T hese stub shafts have threaded parts 39 received in correspondingly threaded openings of bosses 40 of the casing head 12. The other ends of the stub shafts 38. are reduced and received in bearing openings 41 of the wall The casing 14-15is provided with internal gear teeth 42 near the edge thereof adjacent to the casing head 12. These gear teeth are in mesh with the gears 37, so thatthe casing cylinder is rotated as the gears 37 turn. Mounted upon toe casing cylinder 14-45 is a belt band 43 having peripheral radial flanges 44 to prevent lateral displacement of the belt. It will be understood that lot) the power is delivered by the engine from the belt and tending to hold the same in pothrough openings 61 of sition against displacement in one direction. The casino head 12 has a central boss 46 having a ilireaded opening in which is received an adjustable- -thrust bearing 47 having a rounded head 48 in contact with the from a series of turbine inlet nozzles 54 tow the outlet openings 55 of the exhaust cylinder. Adjacent to the inlet nozzles 54, the turbine cylinder has a suitable igniting device 56 consisting of spark plugs included in a suitable electric circuit, or any other means adapted to the purpose. The inlet nozzles 54 of the turbine cylinder which remains fixed are successively in communication with the working chambers formed by the rotating elements. The casing head '13 has an annular extension 57 in which is an annular inlet passage 58 communicating with an inlet conduit 59 which serves to conduct a fuel mixture to the motor. The turbine cylinder 29 has a plurality of axial passages 60 therein whichcommunicate with the passage 58 the head 13. The passages 60 lead to and communicate with the working chambers of the rotary elements and serve to permit these to draw into .them a charge, compress the same and deliver it to the turbine inlets immediately after ignition of the charge by the device 56. The exploded gases then rush into the turbine, expanding within the spiral and caus ing the same to rotate, as will be readily understood. The rota transmitted through the pinion 36 and the gears 37, which in turn drive the rotatable cylindrical casing 14-15 as has already been described.

The above described engine is started by simply giving to the casing 14 and 15 a rotary movement. This rotary movement will cause the rotation of the members 30 through the medium of the engagement of the teeth 62 of said members with the inner gearing 61, whereby the gas drawn through-the passages (S0 enters into-the working chambers and exploded at the proper moment, thereby starting the engine.

It should be noted that preferably the two separate turbine elements and their related parts are so arranged that the ignited charges are delivered thereto at opposite points of the motive cycles in order to bal tion of the turbine is 'anoef fiye operation of theengine. Should it be desired furthermore, a greater number of turbine elements may be-employed.

The present form of rotary engine is cooled in the same way as those described in my (so-pending application. In other words, the cooling liquid is introduced between the relatively eccentric rotary memhere, in the spaces other than those comprising the motive fluid chambers. Suitable means are of course provided (not shown), forthe introduction of the water or other fluid.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
